Measurement Techniques Aims and scope

The composition of the State Primary Standard of the unit of absorbed dose and unit of absorbed dose rate of beta radiation in tissue-equivalent material, GET 9-2018, is described and the metrological characteristics of GET 9-2018 are presented. It is shown that that the metrological characteristics of GET 9-2018 conform to modern domestic and international requirements regarding precision and range of reproduction and transmission of the unit of absorbed dose and unit of absorbed dose rate of beta radiation and its transmission to working standards and means of measurement. The technical characteristics and physical principle of operation of an automated extrapolation ionization chamber produced from the components of GET 9-2018 are considered.
